Use of Fuzzy Logic for Engine Idle Speed Control 900594

A novel approach has been investigated for the application of engine idle speed control. The control method implemented, “Fuzzy Control”, has the advantage of not requiring the knowledge of a mathematical model of the controlled object and is also more robust and flexible than traditional approaches. The experimental results obtained with this method are compared with those obtained with an optimal linear quadratic controller and with those of a conventional PID controller. They indicate that the former has similar capabilities with respect to the optimal approach and better results than the conventional control.
